To all whom it may concern Be it known that I, IIERMANN A. VVENDE, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Belldfinging Mechanism, of which the following is a specification.

This invention relates to a mechanism for ringing bells, chimes or the likeand has for its object to produce a mechanism for this purpose which is efficient and reliable 1n its operation, which is capable of producing either a comparatively loud or soft tone, and which rings the bells at regular intervals.

In the accompanying drawings: Figure 1 is a front elevation of a bell ringing mechanism embodying the preferred form of my improvements. Fig. 2 is a vertical longitudinal section of the same, on an enlarged scale, taken in line 2-2, Fig- 1. Fig. IS a fragmentary vertical transverse section, on an enlarged scale, taken in line 38, Fig. 2. Fig. a is a fragmentary vertical transverse section taken in line 44, Fig. 2 looking rearwardly. Fig. 5 is a similar view taken in line 5-5, Fig. 2, looking forwardly.

Fig. 8 is a fragmentary vertical longitudinal section of the machine similar to Fig. 2 and showing the means whereby the stroke of the hell hammer operating mechanisin may be shortened for the purpose of modulating ,or softening the tone of the bell. Fig. 9 is a vertical transverse section of the same, on an enlarged scale, taken in line 9-9, Fig. 8. Fig. 10 1s a fragmentary elevation of the means for softening the sound of the bell. Fig. 11 is a fragmentary horizontal section taken in line l1-1l, Figs. 8 and 9. Fig. 12 is a fragmentary vertical longitudinal section of the machine taken in line 1212, Fig. 1 and showing those parts thereof which are designed to produce acontinuous tolling of a bell. Fig. 18 is a plan view of the switch mechanism associated with this bell tolling mechanism whereby the electric circuit controlling the operation of this mechanism is automatically opened and closed.

Similar characters of reference indicate corresponding parts throughout the several views.

1 represents the main frame of the bell ringing mechanism which may be of anv suitable construction to support the working parts thereof. Arranged in the central part of this frame and in a transverse row are a plurality of upright bell operating rods or members 2 which are capable of vertical movement and guided at their upper and lower ends in suitable openings formed in fixed upper and lower horizontal transverse guide bars 3, 4 mounted on the main frame while their intermediate parts slide in openings formed in an intermediate guide bar 5 arranged horizontally and transversely of the machine and mounted on the main frame. Associated with each one of these operating rods is a hell 6 which is adapted to be sounded by a device which is operated by the downward movement of the respective rod. When this bell forms one mmeber of a set of chimes the same may be mounted on a support 7 so that it is relatively stationary, as shown in Fig. 8, and the same may be sounded by means of a hammer or tongue 8 adapted to strike the inner side of the same. This hammer ismounted on the upper end of one arm 9 of a vertically swinging elbow lever, the other arm 10 of which is connected by means of a chain 11 or other ise with the upper end of one of the bell operating rods 2. Upon pulling the operating rod 2 downwardly the bell hammer connected with the upper end thereof is caused to swing upwardly and inwardly against the inner side 'or mouth of the bell and ring the same. The weight of the bell hammer when swinging away from the bell operates to lift the operating rod and hold it in its elevated position, the movement of this rod in an upward direction being limited and also made adjustable bymeans of adjusting screw nuts 12 mounted on the lower screw threaded end of this rod and adapted to engage with the underside of the lower guide bar 4, as shown in Fig. 2. That portion of my improved bell ringing mechanism adapted to operate the same for playing a tune or melody is shown in Figs. l.11 and is constructed as follows:

13 represents a plurality of horizontal longitudinal operating bars which are arranged in a transverse row in the front part of the main frame and each of which is 0])- eratively associated with one of the bell operating rods by extending the rear part of the respective operating bar through a slot lei which is preferably formed between the side of the companion operating rod and a loop secured to the adjacent side of this operating rod, as shown in Figs. 2, 5, 7 and 8. Between its front and rear'ends each of the operating bars is so mounted that the same is capable of a limited vertical reciprocating movement and also turning horizontally about a vertical axis. The preferred means for this purpose which are shown in the drawings comprise an upright guide rod 16 which passes through guide openings formed in horizontal transverse guide bars 17, 18 arranged above and below the operating bar and mounted on the main frame, the guide rods of the several operating bars being arranged in a transverse row in the machine. In order to hold each of the operating bars reliably in a horizontal position with reference to its upright guide rod the lower end of each of these rods is connected with the front part of the respective operating bar by means of an inclined. brace 19 as shown in Figs. 2 and 8, thereby producing in effect a triangular structure which is very rigid and prevents vertical displacement of the operating bar relatively to its guide rod. Each of r crating bars and its guide rod are yieldingly held in an elevated position, preferably by means of a spring 20 connected at its lower end with a rearward extension of is lower end of the brace 19 while its upper end is connected with a horizontal transverse bar 2i arranged in rear of the upper part of the guide rod lG'and mounted on the nu.- frame. In the elevated position of this crating bar its rear end is arranged adjacent to the lower end of the guide slot 14 on the com anion bell operating rod while the latter is in its elevated or inoperative position as shown in Figs. 2 and Upon de ore. the operating bar while the parts are in tlie position, its rear end or arm enp'a with the lower end of the slot it in the respective bell operating rod and depresses the latter so that the companion bell hammer strikes blow ainst the bell asso ciated therewith. its soon however as the operating bar is a 11 released the same is raised by means ot its spring 20 into its uppepmost position.

in ore to cushion the upward or return movement of the operating bar and associat d parts and prevent not only undue noise but also arring and wear of the machine means are provided which preferably comprise a piston or plunger 22 formed by the upper end of the guide rod 16 and work i in a barrel or cylinder 23 mounted on the scent part of the main frame. The plun- .1 7 22 1s providedwith a downwardly dished cup-shaped packing 2d so that as thls plun nee too ger descends in the cylinder or barrel 23 the air will be free to pass this packing into the upper part 01? the barrel and thereby avoid retarding the downward movement of the operating bar, but during the upward movement of the guide rod the cup-shaped packing presses the air upwardly in the cylinder and slowly outwardly through an opening or port 25 in the upper end of the barrel. A small quantity of air also enters the barrel through the port 25 during the downward movement of the plunger. This port is covered more or less to regulate its capacity. preferably by a bendable copper disk 26 secured to the top of the barrel over the port 2:) and adapted to be moved toward or from the same to vary its effective area. The upward movement of each operating rod is limited by a stop device which is preferably made adjustable so as to permit of accurat ly timing the sounding of the respective bell. The preferred means for this purpose which are shown in Figs. 2 and 5 comprise a screw bolt 27 having its lower threaded part engaging with a threaded queuing 28 in the he dot the upper end of the barrel while its upper threaded part passes loosely through an opening 29 arranged in a supporting bar 30 mounted on the main frame and arranged over the upper end of the cushion barrel,-a screw nut 31 arranged upon the central threaded part of the bolt 27 and engaging with its underside against the top of the barrel head through the medium of the valve dish; 6 while its upper side be? *e against the underside of the sup porting bar 30, and an upper screw nut 32 arranged on the threaded upper part of the bolt 27 and engaging with the upper side of the supporting bar 30. At the end of the ripard stroke of the operating bar the upper side of the plunger 22 engages with the lower end of the stop screw 27, thereby arresting the further upward movement of the stop bar. Upon loosening the screw nuts 81, 32 the bolt 27 may be screwed up or down in the head of the barrel for changing the position vertically of the lower end of the bolt 27 and thus varying the position at which the operating bar comes to rest dur ing its upward movement by eng gement of the upper end of the plunger 22 wlth the adjusting screw 27. After the screw 27 has been adjusted to the desired position the same is again held in place by tightening the screw nuts 31, 32 against opposite sides of the supporting bar 30.

The depression of e eh one of the operating bars 13 and the respective operating rod associated therewith is effected by engagement with the upper side of the rear end or arm of this bar by one of a plurality of tappets which project laterally outward at intervals from an endless carrier or belt 34 which is preferably constructed in the form of a chain and passes with its up per and lower turns around upper and lower sprocket or supporting wheels 35, 36

forming a vertical operative front stretch of this belt and a vertical inoperative rear stretch. A row of such tappet carrying belts is arranged transversely in the rear part of the main frame behind the operating bars and rods, the several upper sprocket wheels being mounted on an upper horizontal shaft 3 which is journaled transversely in suitable bearings on the upper part of the main fram while the lower sprocket wheels 36 are mounted on a horizontal shaft 38 turning in suitable bearings on the lower part of the main frame. l/Vhen the machine is in operation, the tappet belts are moving constantly in a direction in which the front operative stretches of the same descend and the inoperative stretches thereof ascend. Motion may be imparted to these tappet belts in any suitable manner, the means for this purpose shown in the drawings consisting of an electric motor 39 mounted on the right hand side of the main frame and having its shaft 10 provided with pinion 41 which meshes with a gear whee] 4.2 on the corresponding end of the upper shaft of the tappet belts. The opposite end of the upper tappet shaft is preferably provided with a fly wheel 43 so as to e these belts to run uniformly notwithstanding that the load placed upon the same may be irregular.

In the normal inoperative position of each operating bar its rear end or arm is arranged on one side of the path of the tappets the companion tappet belt, as shown in Fig. '7, in which position of the parts the tappet belt moves idly and does not affect the position of the companion operating bar and the bell associated therewith. When. however the operating bar is turned horizontally about the guide rod 16 as an axis, so that the rear end of this bar is shifted into the path of the companion set of tappets, the next following tappet immediately above the operating bar will ci'igage with the upper side thereof and more the same downwardly together with the operatingrod connected therewith and c: the hammer associated therewith to strike the companion bell. The operating har ren this in engagement with the respective tappet a su'llicient length of time to produce the desired stroke of the bell hammer and then moves laterally out of engagement from the operative tappet so as to permit the operating bar to again rise under the lifting action of the spring 20 as the same drops away from the bell. The tappets of the respect tappet belt engage with the companion Opflliltlflf arm on the vertical operative stretch of this belt so that these tappets remain. fully in engagement with this operating bar during the entire stroke of the bell hammer and therefore produce an eifective blow of the same against the bell. The tappets on the tappet belt are also arranged comparatively close together so that the operating arm will be engaged by a tappet immediately after the operating bar is moved into the path of the tappets, thereby causing the bell to be sounded promptly without any appreciable loss of time and causing the chimes to be rung with practical regularity or uniformity.

Each of the operating bars when turned horizontally into an inoperative position or out of the path of the companion set of tappets is positively held in this position by means which preferably comprise a vertically swinging detent catch or latch 4:4: mounted on the front part of the frame and provided with a shoulder 45 on the underside of its free end which engages over the upper end of a detent finger 4L6 projecting upwardly from the front end or arm of the respective operating bar and preferably forming an upward projection of the respective brace.

The front end or arm of each of the op erating bars projects forwardly through an upright slot 47 formed between adjacent upright bars on the front part of the main frame. lVhile this bar is in its uppermost position the same is engaged by a pressing device which engages with that side of the operating bar opposite to that which it is engaged by the shoulder of the latch 44 so that when the latter is released from the operating bar the same will be turned in a direction for moving its rear end into the path of the companion set of tappets and sounding the companion bell. This pressing device preferably consists of an upper inclined arm 48 which is pivoted on the adjacent part of the main frame so as to swing transversely of the machine about a horizontal axis while its upper part is pressed against the front part of the operating bar by a spring 49 connecting this presser arm with the adjacent part of the main frame. The release of the latch 44 is preferably effected by electrical means those shown in the draw ings consisting of an electro-magnet 50 mounted on the main frame and having its poles arranged opposite an armature 51. attached to the upperside of said latch. The circuit of this electric magnet contains a battery 52 or other source of electric energy and this circuit is adapted to be closed by a switch which may be variously constructed but as shown in ig. 2 preferably comprises a fixed terminal. or contact 53 connected with one side of said electric circuit and a movable terminal or contact 54 connected with the other side of this circuit and adapted to engage with the fixed contact for closing the circuit. Upon closing this circuit, the

electro-magnet becomes energized and lifts the latch ll, thereby releasing the front end of the respective operating bar and permit ting the spring 49 to move the upper pres- '1 and the front end of the operating ontally in a direction which will cause the rear end of this bar to move into the path of the tappets, thereby causing the next following tappet to engage with the respective operating bar and depress the same together with the operating rod associated therewith and ring the companion bell. As shown in Fig. 2, the fixed COHtZl-Qt is mounted on the upper part of a stationary supporting bar of insulating material and the movable contact 54 is arranged at the upper end of a vertically swinging arm 56 which connected by means ot a coil spring 57 with this supporting bar. This last mentioned spring operates constantly to swing the movable contact 54: away from the fixed contact 53, the movement in this direction being limited by means of a staple 5S bracing this arm and secured tothe supporting bar 55 which staple also serves as a guide for this arm. The several switches of the electro-magnets 50 associated with the latches which control the operating bars are preferably arranged. in a row and each switch arm 56 is arranged in front of one of the hammers 59 of a piano or similar hey board mechanism, so that upon depressing a particular key the corresponding hammer tlr of will strike the switch arm and nimc the same rearwardly for closing the circuit oi the particular electro-magnet 50 which controls the ringing oi the bell correspond. to that particular key. This key board mechanism is not shown in the drawings inasmuch as it may be of the usual and well known hind now commonly found in pianos. it preferable to use this ringing apparatus in connection with such a key board, inasmuch as it permits of playing the chimes by merely operating the key board in the 0rdinary manner 01"" playing a tune on a piano or organ. ll desirech however the circuits of the several electro-mag" closed by a switch mechanism o1" any other suitable construction.

After the operating bar has pressed a sufficient distan" a to cause hammer to ring the bell associated with the operating bar is t-.. "ed horizon tally in the opposite direction ing its rear end from the respective tapp which engages the same. This is preferably accomplished by engaging the front end of the operating bar with a lower pressing device which is arranged at the lower end of the slot 47 in which. the front end of the op erating lever moves and which serves to shift the operating bar in a direction opposite to that in which it was shifted by the action oi. the spring 49 of the presser arm l8. This iror disengagranged that it serves stop which engages with the adjacent wall of the slot 47 in which the operating arm moves and thereby limits the swinging movement of the lower presser arm and the action of the spring 61, as shown in Fig. l. The instant the lower presser arm 60 turns the operating bar horizontally sulliciently to disengage its rear end from the operative tappet cat the tappet belt the spring 20 instantly raises the operating liar and the parts associated therewith. Durin the last portion of this upward movement of the operating bar its front end engages with the inclined upper presser arm 48 and. deflects the same slightly so as to strain its spring l9, and the upper end of the detent linger on the operating arm reengages the shoulder of the companion latch which is now in its depressed position, thereby holding the operating bar in its inoperative position preparatory to per forming another cycle ofoperations.

Means are provided for holding the op erating bar in the path of the tappets during the downward movement of this bar a suthcient length of time to insure a full stroke of the bell hammer against the bell and also to hold this bar in its inoperative position during its upward or return stroke so as to prevent interference of the clownwardly moving tappets therewith and also insure engagement, of the detent finger of the operating bar with the latch 44. For this purpose an upright guide is arranged adjacent to the right hand side of the rear part of each operating bar this guide being referably composed of upper and lower sections 63, 64: and mounted on a transverse suppoi ting plate 65 secured to the adjacent part of the main frame. is each operating bar is turned by the spring of the upper presser bar 4L8 horizontally in a direction for carrying its rear end into the path of the companion tappets this rear end swings over the upper end of the upper guide section 63. [is the next following tappet with the upper side of the operating arm and presses the same downwardly an inclined face 66 on the underside or edge-0t the rear end of the operating arm engages with the correspondingly inclined face 67 at the up per end of the upper fixed guide section 63, as shown in Fig. 9 thereby causing the rear end of the operating bar during its continued downward. movement while in en gagement with the underside of a tappet to be forced laterally to a greater extent underneath the respective tappet so that these parts engage with each other over a greater surface and insure a more reliable action of the bell ringing mechanism. The rear end of the operating bar is thus held underneath the active tappet by the front faces of the upper and lower guide sections 63, 64 past which this end of the operating bar slides during this time until it reaches the lower end of the lower guide section. At the same time that the rear end of the operating bar passes below the lower end of the lower guide section 64 its front end engages with the inclined lower presser arm 60 and. is shifted laterally by the same so that the rear end of the operating bar is disengaged from the active tappet and moved underneath the lower end of the lower guide section (34 and in line with the rear side thereof. This operating bar is now raised by the action of its spring 20 and during this upward move ment its rear end slides upwardly past the rear sides of the lower and upper guide sections 63, 64 and is thereby held positively out of the path of the tappets so that but one sounding of the bell is insured. The guide sections hold the operating bar in this turned position until the front end of this bar engages the upper presser arm and the detent finger has rei ngaged the shoulder of the latch 44:, this rengagement of this finger and latch occurring during the last part of the upward movement of the operating bar and just before the rear end of the operating har passes above the upper edge of the up per guide section 63.

. F or convenience in setting up the machine the upper presser arms 48 are provided with upwardly facing shoulders 68 which are adapted to engage with the lower edges of the front ends of the operating bars and. hold the same together with the associated parts in an elevated position, but these shoulders serve no purpose after the ma alrine is set up.

\V hen it is desired to modulate or soften the time o sound of the bell when the same is :--..rucl by the hammer. means are provided shortening the downward throw of each operating rod and thereby reducing the intensity or power of the blow of the bell hammer against the hell. The prefor this purpose which are n in Figs. 2 8 and f) are constructed as follows:

The upper guide sect on (3 is fixedly mourtcd on the supporting plate (35 while the lower guioc section 64- is pivotally mounted at its lower end on this plate so as to be capable of swinging tra nsvorscly about a horizontal longitudinal axis so that this lower uide section may be either brought 'ition in which it forms a downward extension of the upper guide section 63, as shown by full lines in Fig. 9, or the same may be swun laterally away from the upper guide section as shown by dotted lines in the same figure, in which last mentioned position of the lower guide section '1 he same is inoperative and only the upper guide section is utilized to control the operating bar. The lower guide section yieldingly held in line with the upper guide '1' tion when the same is not required for use but positiicly locked in line with the upper guide section when the same is in use. The yielding means for this purpose preferably consists of a spring 70 secured at one end to a lug 71 on the supporting plate and bearing against the rear side of the lower guide section beyond the place where the latter is engaged by the rear end of the companion operating bar. The means for holding the lower guide section rigidly in line with the upper guide section comprise a horizontally swinging latch or catch 72 which. is pivoted on the adjarent part of the supporting plate 05 and prorided with a shoulder 73 which is yieldingly held in engagement with a pin, projection or shoulder 74 on the rear edge of the lower guide section, as shown in Figs. 8 and 11, by means of a spring 75 bearing at one end against this latch and at its other end against stationary part. This catch or latch may be released or disengaged from the pin of the lower guide section in various ways but this is accomplished by electrical means which comprise an electro-magnet 76 mounted on the supporting plates and having its poles arranged opposite an armature 77 on the back of the latch 72, and a switch plug or member 78 adapted to connect two contacts 79, 80 for the purpose of closing an electrical circuit which includes the electro-magnet 76 and a. battery or electric generator 152, as shown in Fig. 8. When the swit h member 78 withdrawn so as to break the circuit across the contacts '79, 80. the clectro-magnet is tlziziinergized, thereby permitting the latch 72 to lock the lower guide section rigidly in. its

op rative position in which i forms a downu: l continiuition of the u rward guide sec tion so that when the companion operating bar is moved downwardly by one of the eorr sponding sets of tappets, the rear end of this operating bar will be compelled to travel downwardly along the entire front faces of the upper and lower guide sections before the rear end of this operating bar can be moved laterally out of engagement from the respective tappet by the pressure of the lower presser arm 60 engaging the front end of the operating bar and turning the same that its rear end moves laterally across the lower end of the lower guide section immediately upon passing below the same. A long downward pull on the operating rod is thus produced which causes the bell hammer to swing with a powerful or heavy stroke toward the bell and strike the same for producing loud sound. Upon shifting the switch member Y8 so as to connect the contacts 79, 80, the circuit through the electro-magnet will be closed that the latter is energized and releases the lower 'uide section by withdrawing the latch {2 out of engagement from the pin 74:. When the lower guide section is thus unlocked by the latch 72 the rear end 01 the operating bar, after it moves downwardly ale the front side of the upper guide section under the downward pressure oi a tappet and clears the lower-end of this guide section, is pressed laterally out of engagei'nent from the operative tappet by the lower prcsser arm 60 and caused to move laterally rearward across the lower end of the upper guide section 63 and then moved vertically upward alom he rear side oi this section to a position 7 above the upper end thereof under the action of its spring 20.

lVhile the rear end of the operating bar thus swings laterally past the lower end of the aner uide section the lower uidesection i A. i D 7 2'3 u .=s dchectcd in opposition to the resilience of itsspring 70, but when the operating arm has again cleared this lower guide section this spring again returns the same to its normal vertical position in which it is alined with the upper guide section. The movement of the lower guide section under the action of its spring may be limited in various ways, for instance as shown in Fig. 9 by a-pping the upper end of the lower guide section past the lower end of the upper guide section. When the operating bar only moves downwardly and upwardly around the upper guide section, the downward stroke of the companion operating rod is shortenech thereby pro ucing a less vigorous pull on the bell hammer and causing the same to strike a lighter blow against the corresponding hell. 7

In order to further diilereutiate the el'lect of the hammer blow agaist the bell for producing either a loud or soft tone means are provided whereby the bell hammer may strike either directly against the bell for producing a loud sound during a long pull oi? the operating rod or a cushioning member may be interposed between the bell and the bell hammer during a short pull of the operating rod so that the bell hammer engages indirectly with the bell and therefore produces a modulated or softer tone. The preferred means for accomplishing this purpose which are shown in Figs. 8 and 10 comprise a cushion ,member 81 preferably consisting of .a strip 01": leather which is connected at its lower end by means of a link 82 with the upper end of the compan ion operating rod while its upper end is con nected with anopen yoke83, the latter bemg in turn connected by a spring 8% with a strip is arranged on the innerside of the bell,

VJ hen a short downward stroke of the operating rod is produced the cushioning strip 81 is also pulled downwardly in opposition to the spring 84 but only to a moderate extent, so that the same remains in the path of the bell hammer and causes the latter to strike the bell indirectly-by reason of the cushioning strip being interposed between these parts at this time, thereby pr0 ducinga soft or modulated tone of the bell. l hen, however, a long downward pull of the operating rod on the bell hammer is produced the cushion'strip is pulled down wardly a greater extent and caused to clear the path of the bell hammer so that the latter strikes directlyagainst the bellthrough the open yoke 83 above the cushion strip, thereby producing loud tone.

ll hen it is desired'to toll a bell continu ously without requiring continuous manipulation ofthe key board my improved bell ringing mechanism is organizedas shown in 'lligs. 12 and 13. Inasmuch as only one of such bells 1S usually required this mechanism can be incorporated in the same machinewhicli operatesto ring a set of chime bells. This bell tolling mechanism is constructed as follows:

86 represents a horizontal rock shaft upon which the tolling bell 87 is mounted and which is provided with a drum or wheel 88 the periphery of which is connected by a line, cord, cable or other flexiblemember with the upper end of an operating rod 89 similar to the operating rods used in connection with the chime ringing mechanism. The lower part of this tolling operating rod is guided similar to the chime operating rods 2 and is provided with a loop 90 which receives the rear end or". an operating bar 91 secured to a vertically movable guide rod 92 which latter is guided. adjusted and cushioned in its vertical movementsby the same means as thoseshown in Fig. 2 with reference to the guide rods 16. This operating bar and the parts associated therewith are yieldingly held in an elevated position by means of aspring 93. The depression of the operating bar is ellected by one of a series of tappets 94 similar to those shown in Fig. 2, the operating baris held turned in a position in which its rear end is arranged above the rear side of a vertical guide 95 bynieans of a latch 96 engaging with a detent finger 97 on the front end or" the operating bar and an, electromagnet .98 is adapted to attract an armature 99 on the latch 96 similar to the construction shown in Fig. 8, and an upper and lower pressing device is however associated with the front end of this operating bar similar to the upper and lower presser bars shown in Figs. 1 and. 2. The guide 95 in the telling mechanism is prefei ably made in one continuous piece instead of being made in sections. 100 represents a segmental electric contact mounted on a fixed support adjacent to the tolling bell and concentric therewith and 101 is a movable flexible contact arm mounted on the adjacent part of the bell shaft and adapted to engage with the fixed contact 100 during the rocking of the bell in a forward direction but to be disconnected therefrom as the bell. swings in the opposite direction. These contacts 100-101 form part of an electric circuit which includes the electromagnet 08 and a battery 102 or other electric generator. This circuit also contains a make and. break device or switch which comprises an upper contact 103 mounted on a relatively fixed support and a lower contact 104 which is carried by the companion operating har 91. Adjacent to the segmental fixed contact 100 is arranged a, segmental row of oblique guide plates 105 which are free at their inner ends and supported on a fixed bracket 10 at their outer ends. \Vhen the bell is at rest the contact arm 101 is arranged adjacent to the segmental contact 100 but out of engagement therewith and also adjacent to the front end of the row of guiding or deflecting plates 105, as shown in Figs. 12 and 13. The initial forward rocking movement of the bell is effected by closing the circuit containing the battery .102 and the electroanagnet 98 by hand this being effected by engaging the contacts 107, 108 of a switch the members of which are connected across the circuit of the battery 102 and electro-magnet 98, but thereafter the circuit of the magnet is opened and closed intermittently by the operation of the switch conta its 100. 101 and the switch con tacts 103 101. 1' inning that the bell is at rest and it is desired to toll the same, the iirst operation is to engage the contacts 107, 108 oi the starting switch. thereby closing the circuit through the electro-n'iagnet 98 and causing the latter to lift the latch 00 out of engagement from the companion detent finger and permit the rear arm of the respective operating bar to swing laterally underneath the not following tappet associated therewith. s the latter descends and carries the operating bar downwardly with it this bar slides past the front side of the guide 05 and upon reaching the lower end oii this guide this operating bar is moved across this lower end and out of engagement from the respective tappet and then slides upwardly along the rear side of this guide to its uppermost position in the same manner as described with reference to the constructionin Fig. 2. During the last portion of the downward movement of the operating bar the same strikes the lower end of the loops 00 causing the operating rod 89 to be pulled downwardly, thewheel S8 to be turned and the bell 87 to be swung forwardly or in the direction of the arrow indi ated in Fig. 12. During the downward movement of the tolling operating bar the switch contacts 108, 104 are separated so as to break the circuit through the electromagnet 08 but during the last part of the upward stroke of the operating bar under the action of its spring 03 the contacts 103, 104-, are again engaged. During the return or backward swing of the bell the same, owing to its weight, passes rearwirdly beyond its central or neutral position so that the contact arm 10] slips past the rear ends of the set of oblique guide plates 105. After the bell has completed its backward swinging movement and begins its next forward stroke, the contact arm 101 is guided by the adjacent inclined guide plate 105 laterally toward the fixed segmental contact 100 and caused to engage the same, thereby again ch ing the circuit which includes the batterv 102 and the elcctro-inagnet 08 and cansing the operating bar 01 to be released and swing with its rear end horizontally into the path of the tappets so that the latter as they descend produce another working downward stroke of the operating bar and an operative or effective forward stroke of the bell. During the first part of the down- I war movement of the operating bar 91 the ch 'c circuit is again broken between the tarts 10 101 notwithstanding that this circuit remains closed temporarily by en pgement of the contacts 100, 101. In this manner the hell 8? continues to toll intermittently so long as the motor is in operation and. moves the tappets inasmuch as the electric circuit for operating the electromagnet 05% is closed when the operating bar reaches the end of its upward stroke and the tolling bell effects the initial portion of its forward stroke, while the circuit is broken at all other times. thereby automatically tolling the bell 87 at regular intervals.
